When I ride into my new bike the fork doesn't shrink. My weight is about 81kgs. I think good forks usually shrink to 75% of its length. In my case it does not shrink at all.
The fork is cheap. Does not have any preload settings with it. Also is does not have lockout functionality.
Is there any way to make it softer? Maybe by opening it and do some hacking. Not sure though.
The fork manufacturer is Zoom. Here is the details.
My fork is same. Except its color is white.
